8.4 Compass Calibration
8.4.1 Compass Calibration
(1) Put aircraft to the horizontal position to lock the motors ( lock method refer to 8.3.2).
(4) Please reconnect the aircraft power after calibration.
8.4.2 Notes:
(5) Please reconnect the power of the aircraft and recalibrate the Compass if crash.
(3) Rotate the QR X350PRO 360 degree according to forward/backward, left/right and horizontal level orientation(please
follow the figures) and leave it on the horizontal place for 30 seconds, the left green LED flash quickly till
light out which means calibration finished.
ELEV stick
(5) After calibration, first time taking off, the aircraft may drift in the sky, please just ignore that, and
meantime the system will do compass calibration automatically. After 3-5 minutes flight, please land
the quadcopter on the ground and hold the motor in order to save calibration parameter.
Please inspect the motors lock or not before calibration. The factory default setting for the motors are
locked after finished ID binding. If the aircraft need to re-calibration after flight, it is a must to lock the
motors again before calibration.
After successful calibration for QR X350PRO, it's just plug and play to use.

Basic Flight
Instruction
Mode 2: Keep the throttle/rudder sticker to the lowest
position and move to the right side, then push the Elevator
stick to the lower left corner, compass calibration mode
entered.
(2) Mode 1: keep the throttle stick at the lowest left corner
and push the elevator and rudder stick to the lower right
corner, compass calibration mode entered.
The following condition need to calibrate the compass:
(1) The first time for flight, it takes longer time to inspect the GPS signal.
(2) When you are in a new environment.
Forward & backward 360
rotation(Rotate the aircraft, from
0 to 90 ,180 , 270 , 360 , all
need to pause for 1 second.)
Leftward & rightward 360
rotation(Rotate the aircraft, from
0 to 90 ,180 , 270 , 360 , all
need to pause for 1 second.)
Horizon level 360 rotation(Rotate
the aircraft, from 0 to 90 ,180 ,
270 , 360 , all need to pause for
1 second.)
Vertical direction(Head down)
rotation 360 (Rotate the aircraft,
from 0 to 90 ,180 , 270 , 360 ,
all need to pause for 1 second.)
(2) Please re-calibration the compass, if circles appear during the flight.
(1) Please keep away from magnetic matrials area to calibration.
(3) Please recalibrate the compass if it is replaced or the vehicle position is changed.
(4) Please check whether there is a strong magnetic field nearby disturbing the compass if the calibration is
failed constantly.
